It would have been AWESOME if Jo had mentioned Cindy in that one episode where Jo comes into the girls' room in season 3 or 4 over the kitchen with her hockey stick, freshly grimy from a game (you remember that?). The writers could have given we Lost Girl fans a treat by saying something like, "Man, that Cindy is one tough cookie. It took me three matches to finally wipe her out!"
(or whatever you call a match/round in a hockey game
)
